Analysis of corrosion rate of buried API 5L× 70 steel pipeline in soil by Taguchi technique


Author(s): CI Nwoye, B Imamudeen and CN Nwambu

Abstract: Several studies have identified corrosion of buried steel pipeline to be attributed to certain factors in the soil such as: salt concentrations, type of soil, temperature, pH, moisture content, earth currents, welded joint and microorganism. In this study, Taguchi design of experiment was used to optimized three factors (pH, clay content and moisture content), having three levels each. Corrosion test was conducted to determine the corrosion rates of the samples. The results of analysis showed that S/N ratios significantly affected the corrosion rate by the levels in the Taguchi orthogonal array. It was established that clay content is the major influential parameter affecting the corrosion rate. The optimized corrosion rate parameters for the smaller-the-better criteria are clay content 1 wt%, pH 4-8, and moisture content 20-40%.
